Neural control of rhythmic arm movements
In this paper we present an approach to robot arm control based on exploiting the dynamical properties of a simple neural network oscillator circuit coupled to the joints of an arm. The entrainment and input/output properties of the oscillators are used to perform a variety of tasks with the same architecture, without any modeling of the arm or its environment. The approach is implemented on tw...
متن کاملComparison of external load compensation during rhythmic arm movements and rhythmic jaw movements in humans.
Experiments were performed on human elbow flexor and extensor muscles and jaw-opening and -closing muscles to observe the effect on rhythmic movements of sudden loading. The load was provided by an electromagnetic device, which simulated the appearance of a smoothly increasing spring-like load. The responses to this loading were compared in jaw and elbow movements and between expected and unexp...
متن کاملRhythmic robot arm control using oscillators
This paper presents an approach to robot arm control based on exploiting the dynamical properties of a simple oscillator circuit coupled to the joints of an arm. Using the same architecture, a wide variety of tasks can be achieved without any explicit modeling of the arm or its environment. The inherent properties of the oscillators give robustness to perturbations and changes in frequency. The...
متن کاملLocomotor-Like Leg Movements Evoked by Rhythmic Arm Movements in Humans
Motion of the upper limbs is often coupled to that of the lower limbs in human bipedal locomotion. It is unclear, however, whether the functional coupling between upper and lower limbs is bi-directional, i.e. whether arm movements can affect the lumbosacral locomotor circuitry. Here we tested the effects of voluntary rhythmic arm movements on the lower limbs. Participants lay horizontally on th...
متن کاملGenealogy of Rhythmic Ritual Movements with Samaacheh
In this article, the authors make an attempt to re-examine the neglected portions of ritual-artistic dance by presenting new evidence and using paid theories through phenomenological study of this art. The fundamental results of the present study, which will be obtained by a quantitative phenomenological and an interpretivehistorical approach, the social and religious contexts of this pervasive...
